自嵌式挡土墙在长江航道整治工程中的应用

以荆江航道整治工程周天河段新厂高滩守护工程下段混合式护岸中自嵌式挡土墙试验段为依托工程,分析其在长江航道整治中的适应性。经过一个洪水期冲刷后,根据监测数据统计自嵌式挡土墙墙体最大水平位移量小于20 mm,最大沉降量小于15 mm,即自嵌式挡土墙初步适应了长江航道复杂的水流冲刷条件,满足护坡的设计效果,为其在长江航道整治工程中进一步推广应用奠定了基础。

Application of auto-inserted retaining wall in Changjiang waterway engineering

This paper analyzes the adaptability of the auto-inserted retaining wall in the Changjiang waterway engineering relying on the high beach protection project in the Xinchang Zhoutian waterway. After one high flow season,the monitored results show that the lateral displacement of the retaining wall is limited to 20 mm and the maximum sedimentation is smaller than 15 mm. It reflects that the auto-inserted retaining wall can preliminary adapt to the complex flow scour condition and fulfill the design requirements,which builds a foundation for its further extending application in Changjiang waterway engineering.
